My husband and I having ttc now for almost a year. I suffer from very irregular periods and especially after I had the implant birth control removed last March. My last period was for about 2 weeks over the new year. Since the end of that period we have been having intercourse near enough everyday. Having no idea off when my period would be due exactly, with a guess of when my last occurred it should be now in the next few days. But since Saturday 18th I have been having very light pink or brown coloured discharge on an off. Somedays I could have nothing at all, all day then a wee bit the next again. I'm very confused. Getting BFN when I test with clearblue (non digital).

Are we just wishful thinking or could I be pregnant? Best home testing kits to buy? Any advice at all?
